springboot global character encoding settings

1, arranged in application.properties

#编码格式
spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8

2, their handwriting encoding filter

//字符编码过滤器
@WebFilter(urlPatterns = "/*",filterName = "CharacterEncodingFilter")
public class CharacterEncodingFilter implements Filter{
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }
 
    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) servletRequest;
        HttpServletResponse response = (HttpServletResponse) servletResponse;
        request.setCharacterEncoding("UTF-8");
        response.setCharacterEncoding("UTF-8");
 
        filterChain.doFilter(request , response);
    }
    @Override
    public void destroy() {
    }
}

3, using java to write a character encoding configuration configuration class

/**
 * 中文乱码解决
 */
@Configuration
public class CharsetConfig extends WebMvcConfigurerAdapter {
    @Bean
    public HttpMessageConverter<String> responseBodyConverter() {
        StringHttpMessageConverter converter = new StringHttpMessageConverter(
                Charset.forName("UTF-8"));
        return converter;
    }
    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        super.configureMessageConverters(converters);
        converters.add(responseBodyConverter());
    }
    @Override
    public void configureContentNegotiation (ContentNegotiationConfigurer configure) { 
        configurer.favorPathExtension (false); 
    } 
}

　　StringHttpMessageConverter is a transcoder request and response information from source we found default encoding ISO-8859-1, UTF-8 is not, so we just above configuration request string can be converted to UTF-8.

WebMvcConfigurerAdapter is springmvc configuration of a dominant class, the method we are interested in we can achieve.
